The previous control methods are feasible only when the fuel cells model is accurate enough and the controllers were developed assuming a perfect knowledge of the operating conditions for the fuel cell system. Plant uncertainties, such as changes in the membrane properties over time or variation in the ambient temperature, can affect the performance of the resulting control system, and, hence, more robust control design techniques should be investigated to guarantee system performance. In addition, most of the mentioned control algorithms are aimed at the PEMFC electrical power control, while the PEMFC temperature control is taken as supplement for power control, not even to consider the coolant circuit control design. Therefore, it is necessary to develop an accurate and simple coolant circuit model, and find suitable control method for dynamic temperature control. Generally, circulating coolant can be applied in removing the excess heat of the PEMFC whose electrical power exceeds 5 kW [23]. In order to efficiently control the PEMFC temperature, a coolant circuit of a PEMFC is modeled based on the physical molar conservation principles and the energy balance theory. However, the performance of the generalized controller largely depends on the availability of an accurate model. As a consequence, the application of conventional control strategies may lead to unacceptable closed loop performances. The controller must be robust to uncertainty in a non-conservative manner and must meet closed loop objectives such as tracking, regulation and disturbance attenuation. Compared with conventional control strategies, fuzzy control is appropriate to use in temperature control applications because it is faster and cheaper to develop and easier to implement. It takes the advantage of the synthesis of the knowledge which is provided by human expertise (in the form of IFeTHEN rules), especially when the process model is unknown [24]. So the incremental fuzzy control with integrator technique is designed according to the established model and control experience rule. The PEMFC temperature and coolant inlet temperature are controlled by regulating the circulating coolant flux and bypass valve factor respectively.
